NOTICE:
If a value of a register is changed on the room controller (with buttons), a next write command to "this value" will be ignored,
and the room controller will not reply back anything. Those registers are:
1. Modbus Function 05,15 register address 01.
2. Modbus Function 06,16,23 register address 01~48.
For example, if users re-set the set-point value with buttons, a next Modbus command Fun.06/16/23 reg. address 01 from DDC/
BMS will be ignored and the room controller will not reply back any to DDC/BMS sent. (Note: While a value of a register is chang-
ing on the room controller (with buttons), any write command to "this value" will be ignored, but the room controller will reply
back the same data which DDC/BMS sent.)
This special strategy is integrated because registers must be changeable on both sites (master and slave).
